Open Question: How does my diet plan sound?

Thinking of taking a Protein Shake (EAS 100% whey protein) 30 minutes before my workout, and then eating a DeTour original protein bar post workout (5-20 minutes after workout). Special K Cereal with 1% fat milk for breakfast, and Nature Valley nut bars as snacks. Should I use two protein shakes, pre workout and post workout, instead of Shake / Bar? Or Shake / Bar with another Shake later at night? Age: 17 -- 18 by October Height: 6'0" Weight: 168lbs Ideal daily protein intake: 117g
